[Figure 7.3] Setting example of received data
(a) Frame writing of Frame Editor (b) Ex. of GMWIN program
[Figure 7.3] shows a setting example for frame receiving. Frame name and saving area of received data shall be set
in RCV_MSG(receiving Function Block) of GMWIN program also for data receiving similar to transmission. The
frame written in Frame Editor takes the role of matching receiving protocol and the receiving Function Block of
GMWIN program takes the role of saving data of the applied frame received via Cnet I/F module to receiving data
areas of RD1 ~ RD4. RD data saving area of receiving Function Block as of ARRAY variable has no setting for data
length differently from the transmission Function Block and defines data receiving area by setting the number of
ARRAYs identically to the number of received data.
